Prevention of ocular surgery-induced miosis

Prevention of ocular surgery-induced miosis refers to the maintenance of intraoperative pupillary dilation during anterior segment ophthalmic procedures, most notably cataract extraction and intraocular lens replacement Surgical trauma and mechanical manipulation of the iris trigger local tissue injury, which stimulates the release of endogenous prostaglandins and activation of the iris sphincter muscle, leading to unwanted pupil constriction Prophylactic inhibition preserves adequate mydriasis ...

This acute reduction in pupil aperture impairs intraocular visualization, elevates the technical difficulty of the procedure, and substantially increases the risk of operative complications such as posterior capsule rupture, retained lens fragments, and vitreous loss Prophylactic inhibition preserves adequate mydriasis across the ocular visual axis throughout the intervention
